VISE.

SPECIFICATION forming part of Letters Patent No. 382,360, dated May 8, 1888.

Application filed December 7, 1886. Serial No. 220,883. (Model.) Patented in Germany November 11, 1886, No. 40,233; in Austria-Hungary November 1B, 1886, No. 44,696 and No. 9,611; in France November 30, 1886, No. 169,508; in Belgium November 30, 1886, No. 75,440, and in England December 1, 1886, No. 15,684.

To aZZ whom it may con/cern.-

Be it known that I, CARL JosEF HERMANN, a subject of the German Emperor, and a resident of Bielefeld, in Vestphalia, Prussia, Germany, haveinvented anew and usefullmprovement in Vises, (for which lf have obtained Letters Patent in the German Empire, No. 40,233, dated November 11, 1886; in Great Britain, No. 15,684, dated December 1, 1886; in France, No. to 169,508, dated November 30,1886; in Belgium, No. 75,440, dated November 30, 1886, and in Austria-Hungary, No. 44,696 and No. 9,611, dated November 13, 1886,) of which the following is a specification.

t 5 This invention relates to vises; and its object is to provide a vise with large range of holding capacity and readily and rapidly adjustable. A further object is to enable the vise to be set at any angle iu a horizontal plane.

zo To this end my invention consists in the combination of parts, as hereinafter described,

and specifically pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of my improved vise fixed to the edge of a bench. Fig.

l@ is a vertical section thereof, showing interior mechanism; Fig. 2, a plan view, and Fig. 3 a front elevation thereof. Fig. 4 is a horizontal section on line a b, Fig. 1. Fig. 5

3o shows, partly in section; a modification in which the vise is made adjustable. Fig. 6 is a horizontal section on line :r y, Fig. 5.

Like letters refer to like parts through out the gures.

3 5 The vise consists, essentially, of a fixed jaw, B, and a movable jaw,A. rlhe fixed jaw B carries a foundation-plate, p,by means of which it can be firmly bolted to the upper surface of the bench. To or with the said fixed jaw B is 4o xed or formed in a position vertically below said jaw a bracket, G, extending horizontally forward from the front of the bench,and preferably bolted thereto. Within the bracket C,

and supported partly on a roller, R, journaled in the fore or outer end thereof, slides the U- shaped casing S, holding in its forward arm the movable jaw A, and alsocontaining mechanism, hereinafter described, for xing the posit-ion of the said jaw. The casing S carries,-

also, on the upper end of its rearward arm a 5o horizontally and backwardly extending bar, g, sliding in a sleeve fixed to or forming part with the foundation-platep of the fixed jaw B. In the bracket C, below the casing S, is arranged a rack, z, into the teeth of which projects the catch t', supported between guidingblocks w w in the casing S and operated from the finger-lever d through the connecting-rod e and balance-lever h, pivoted at o. The pin i is normally held in the teeth e by the action 6o of a spring, such asm. On pressing up the lever d the catch t' will be disengaged from the rack z and the casing S will be free to move horizontally. The movable jaw A is fitted loosely into the forearm of thecasingS in such a manner that it has a free play in the direction of the oppositejaw for au amount equal at least to the pitch of the teeth of the rack a. The jaw A is supported partly by the collar a', formed thereon,rest ing on the upper end of'yo the casing S and partly on rails n, arranged at its lower end and fixed to the sides of the casing S. The lower end of the jaw Ais adapted in shape to the rails n,as shown in Fig. 3, and

to it is screwed the plate Q, catching under the 7 5 rails n, so that when another jaw is to be substituted for the jaw A the latter can be removed from the casing by first removing the plate q.

Thejaw A is adjusted in the casing S by the 8o spindle Z, operated in the usual manner.

The operation of this vise is as follows: The hand is placed round the spindle Z, the lever d lifted, and the casing S pulled out to a sufficient eXtent to admit the article to be held be- 8 5 tween the jaws. The casing S is pushed back as far as possible and the leverdreleased. The 4 catch i will then fall into one of the recesses in the rack z and hold the casingS firmly. The spindle is then turned until the article is held go sufciently firmly between the jaws.

In the modification shown in Fig. 5 the casing S is l-shaped andthe bar g is dispensed with. The horizontal arm of the casing S is adapted to slide in the base of the fixed jaw, 9 5 the rack z and the roller R being placed thereunder, as shown. In Figs'. 5 and 6 are further shown themeans for setting the vise at any angle in a horizontal plane. Io the bench is fixed a disk, G, having in its center a cavity, in which is adapted to slide the bolt O, fixed vertically to the under surface ofthe frame P of the vise. The upper surface of the disk G and the under surface of the plate P are provided with corresponding equidistant radial ridges, v' and v, respectively, said ridges being adapted to lock together When the plates P and G are held together. Theboltearriesascrewspindle, O', With thn1nbnut M, and is also surrounded by the helical spring F, tending to force the plates P and G apart.

In setting the vise at any angle the thumbnut Mis partly unscrewed, allowing the spring F to lift the plate P out of engagement with the plate G. The vise can noWbe turned to the necessary angle and the screw M screwed up. The plate P will then engage the plate G in the desired position.

'1. The combination of ajaw, B, having a socket in the frame thereof and a 1aclr,z,in said socket, with an arm, S, having an extension guided in said socket, a tooth in said extension adapted to gear with said rack,lever mechanism for lifting said tooth,and ajaw, A,adjustablein said arm in a direction to and from said jaw B, for the purpose set forth.

2. The combination, of a jaw, B, having a socket in the frame thereof and a rack,z, in said socket, with an arm, S, having an extension guided in said socket-atooth in said extension adapted to gear with said rack, a spring for holding said tooth in engagement, bellcrank lever h, rod e, and lever d, for raising said tooth, a removable jaw, A, adj ust-able in said arm S in a direction to and from said jaw B, and screwspindle Z, for adjustment of said jaw A, in the manner set forth.

3. The combination ofajaw, B, a base, P, in-

` tegral therewith,'a socketin said base, an arm,

S, having an extension movable in said socket, ajaW, A,in said arm,and means for relative adjustment ofjaws A and BWith a spindle, O, on said base P, ribs v on said base, plate G, ribs v on said plate, spring F, and nut M, for the purpose set forth.

In testimony WhereofIhave signed this speciiication in the presence of two subscribing witnesses.
